	Summary:
	This paper presents a comparative analysis of serviceability limit states – vibrations of classic timber floor structures and modern timber floor structures of crosslaminated timber (CLT panels) according to Eurocode 5 (EC5). Based on the numerical analysis can be concluded that the dynamic behavior of CLT floor structures depends on a number of factors of which the most important are two: the longitudinal stiffness and mass of CLT panels. Less influence on the dynamic characteristics with regard to vibration, have factors such as: boundary conditions, thickness of the layers in panel and type of timber. Depending on the longitudinal stiffness and mass, fundamental natural frequency CLT floors structures is usually above 9Hz, which is important considering that the human body is extremely sensitive to frequencies in the range of 4 to 8Hz. Calculation of vibration flooring structures of CLT panels can be simplified in some cases using only the longitudinal stiffness of the panel and mass as authoritative parameters.
